The invention relates to a method for producing a polymer system capable of proton exchange, based on at least one polyaryl ether ketone. Said method consists of: (i) reacting the polyaryl ether ketone(s) with at least one alkane sulphonic acid, to obtain polyaryl ether ketones (I) containing sulphur. The invention also relates to sulphonated polyaryl ether ketones, which can be produced according to the inventive method and to their use as a polymer electrolyte membrane.
L'invention concerne un procédé pour réaliser un système polymère apte à l'échange protonique, ce procédé consistant à: (i) mettre à réagir au moins une polyaryléthercétone avec au moins un acide sulfonique alcane pour obtenir des polyaryléthercétones (I) contenant du soufre. La présente invention porte également sur des polyaryléthercétones sulfonées pouvant être obtenues selon le procédé de la présente invention, et sur leur utilisation comme membrane électrolyte polymère.
